Glass to Metal Seals (hermetically sealed)
Pre-oxidized：A suitable oxide layer is pre-oxidized on the metal
surface as a transition zone. The transition zone thus
enables the properties of the glass to gradually change
to those of the metal.
(Most metals require pre-oxidation)
Annealing：Reduce or eliminate the permanent stress generated during
the forming or thermal processing of glass, and enhance
the strain resistance of glass(lens).
Remove oxide：For optimal surface treatment of metal (electroplating
or electrochemical polishing), the metal oxide layer
must first be removed.
